Abstract
We describe a single beam device that records continuously as a function of wavelength, simple quantities related to the reflectance and transmittance, (1 − R)/(1 + R) and (1 − T)/(1 + T). The unit is easily attached to any spectrometer. It is sensitive to changes in these quantities of about 1 × 10−4, while systematic errors in alignment set an absolute accuracy of about 1 × 10−3.
